I agree that most lotions and potions can be put into regulation-size containers in a Freedom Baggie- but what about alcohol, bought at the destination or in Duty-Free? Those of us who have to connect on re-entering the US are forced to check a bag if we've bought Duty-Free alcohol. Plenty of people on this site enjoy bring back bottles of wine from places they visit.

I used to carefully pack my purchases into my carry-on so they'd be safe from the baggage gorillas and the TSA. Now I can't. No mishaps so far, thank heaven, but if I come home from London and find that a bottle of the single-cask scotch in my checked bag is lost or damaged, my husband may cry. In fact, I've had to spread the risk by putting 2 bottles in my main bag and checking a second, smaller bag for the other 2. (I'm generally on American where I have status, so they carry an extra item and they don't get paid for it.)
